SASH HOLDER AND FASTENER- SPECIFICATION forming part of Letters Patent No. 791,970, dated June 6, 1905.

Application filed January 15, 1902. Serial No. 139,127-

1'0 Z7, whom it may concern..-

Be it known that I, ANDREW WILKIE, J r., a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, haveinvented certain new and useful Improvements in Sash Holders and Fasteners, of which the following is a specilication.

My invention relates to improvements in sash holders and fasteners, the object of my invention being to provide a device of this character which will securely hold the two sashes of a window at any point to which they may be raised or lowered.

My invention is especially intended to prevent entry from the outside through'said window in the case when the sashes are opened a short distance at the top and bottom to ventilate the room.

My invention also is effective in avoiding or at least greatly diminishing the rattling of the window-sashes.

My invention,therefore, resides in the novel constructions, combination, and arrangement of parts for the above ends, hereinafter fully specified, and particularly pointed out in the claims.

In the accompanyingdrawings, Figure 1 is a perspective view of a window equipped with my improved device. Fig. 2 is an enlarged perspective view of the sash-fastener detached. Fig. 3 is a similar View of the gravity-catch detached. Fig. 4 is a similar view of the key-handle. Fig. 5 is a similar view of the escutcheon. Fig. 6 is a similar view of the cam-key. Fig. 7 is a similar view of the block. Fig. 8 is a similar view of the bolt. Fig. 9 is a similar view of the boltframe. Fig. 10 is a similarview showing one of the corrugated strips. Fig. 11 is a side elevation of the sash-fastener as a whole detached. Fig. 12 is a plan view of the same. Fig. 13 is an end view of the same. Fig. 1 1 is a partial cross-section through the camkey. Fig. 15 is a horizontal section through the edges of the window-sashes and through the pulley-stile. Fig. 16 is a broken perspective view of the part of the pulley-stile and of the weather-strip engaged by the device.

Referring to the drawings, 1 represents the upper or outer sash of a window, and 2 the lower or middle sash thereof, divided by the parting-bead 3 and sliding against the pulley-stile 4 in the usual manner between the weather-strip 5 and the stop 6. The pulleystile and the inner edge of the weather-strip are recessed, as shown at 7 to receive the bolt-frame 8 and the bolt 9. The partingbead 3 is cut away on its under side, as shown at 10.

The bolt-frame 8 is formed of a single piece of metal having its outer end bent upward to form an end wall 11 for the lug 12 of the bolt and is then again bent back at right angles parallel with the body of the frame to form a lip 13, extending over the end of said lug. The function of said lip is, first, to prevent the outward displacement of said bolt, and, secondly, to prevent the entrance of dust and dirt and the formation of ice between the end of the bolt and the end wall of the frame, which might prevent the bolt from being extended the full distance to allow the sashes to move freely. A further important result attend ant upon the use of this lip is that by holding the bolt back in place it prevents the vibration of the sash from one side of the window to the other, which might be caused by windpressure even when the sash is clamped by the bolt. I/Vere it not for this lip, although the sash would be held by the bolt against vertical movement, there would be nothing but the parting-bead to prevent horizontal movement of the sash in its own plane. To hold said frame in place, it is provided at its outer end with prongs 14, punched out from the lower portion of the end wall 11 and extending in line with the main body of the bolt-frame. These prongs are driven into the weatherstrip at the end of the recess 7 and thus prevent this end of the bolt-frame from being drawn out of the recess. At the other end the frame is first formed so as to provide supporting and guiding ledges 15 for the feet 16 of the block 17. Then at the extreme end the sides of said frame are bent upward to form standards 18 and then outward to form gageplates 19, resting upon the face of the pulleystile and secured thereto by screws 46. The recess 7 in the pulley-stile is enlarged at the end, as shown at 20, to receive the ledges 15. It will be seen that said enlargement is longer than said ledges. This is for the purpose of permitting the feet 16 of the block 17 to be passed into position between the ledges and the plates 19, between which ledges and plates said feet slide snugly.

Upon the bolt-frame 8 slides a bolt 9, the outer end of said bolt having the lug 12, aiready mentioned, which extends outward at right angles and is provided with horizontal teeth or corrugations 21, arranged when the bolt is moved inwardly to engage similarlydisposed teeth or corrugations 22 on a strip 23, secured to the side of the outer sash at its lower end. for the inner sash, there is provided a block v17. which slides longitudinally of the boltframe independently of the bolt. said block having the feet 16, which, as already mentioned, slide upon the ledges 15 of the boltframe, said block itself sliding snugly between the inner edges of the gage-plates 19. Said block has also the corrugations 24:, which engage corrugations 22 upon a strip 23 on the inner sash. it being necessary that the end of the bolt should slide freely underneath the block while at the same time the feet of the block slide upon the ledges of the bolt-frame, which are on a level with the under side of the bolt, it is necessary to provide connections between said feet and block which will allow this to be done. These connections are formed by means of steps or shoulders 25, which are of sufiicient thickness to form agood connection between said feet and block, and the edges of the bolt, at the inner end thereof, are chamfered to conform to the shape of said stepsthat is to say, they have inner oblique surfaces 26 and outer surfaces 27 parallel with the upper-surface of the bolt. It is to be understood that the edges of the bolt are sufficiently cut away to allow it to slide freely out of contact with the under surface of the block,which rests wholly and independently upon the frame by means of the feet 16. Also it is to be observed that the chamfer in the bolt is cut sufiicient-ly far back to allow the block to be inserted in its operative position.

To impart the above longitudinal movement to the bolt and block, there is provided a key 28, having formed thereon upper and lower cams 29 30 of substantially opposite eccentricity, as shown. The upper cam works in an oblong hole 31 in theblock 17, while the lower cam \vorksin an oblong hole 32in the inner end of the bolt. The upper end of said key passes through a hole 33 in an escutcheon 3 1, secured byscrews 35 to the pulley-stilethrough To accomplish the same purpose.

the stop. The outer plane surfaces of the upper and lower cams being large 'liat surfaces and being held firmly in place between the frame and escutcheon it is not necessary to provide any other rotary bearing for said key besides the hole 33. The upper end of said key-stem is formed with a transverse slot 36, which receives a wedge-shaped rib 37, ex-

tending diametrically across the socket 38 of the handle 39. The handle is driven firmly onto the end of the key-stem, and the wedgeshaped rib enters the slot with great force and firmly secures the block in place. Said handle is formed with a projection 10, which abuts against the heads of the screws 35, and thus limits its movement. Upon said escutcheon, directly above the key 28, is pivoted a gravity-catch 11, the pivot of said catch being passed through a hole 412 in said escutcheon and then upset at the bottom, as shown at 13, said catch having a nose 14:, which engages one of aseries of ratchet-teeth around the socket of the handle, and so prevents said handle being turned except when said catch is raised out of engagement therewith.
